Modern plastics production must combine speed to meet demanding schedules and accuracy to reduce waste and eliminate cost. At Revere Plastics Systems, we employ a suite of injection molding technologies that help speed up production and keep tight control over inventory. One of those methods is stack molding.
What Is Stack Molding?
Stack molding is really any process that uses multiple mold surfaces to create two or more parts in quick succession. While a traditional single-part mold uses two molding surfaces to create one part, a stack mold might use three molds to create two parts or stack even more to create additional parts in one production cycle. The number of molds depends on the size and complexity of the finished product.
When Is It Most Useful?
- For parts that must be produced to work together, stack molding production ensures precisely the right amount of matching parts.
- For high-volume parts, producing multiple products from same shot sizes, stack molding can increase production times, driving cost-savings that eclipse any added mold costs.
- For larger finished parts, stack molding can break them into smaller pieces. These use smaller– and less costly– molds that save money in tooling, while the dual-process nature of the stack mold process doesn’t sacrifice production time the same way a traditional single-mold process would.
